Gas Discharge Tube Arresters (GDT) have a wide variety of applications in industries such as telecommunications, industrial equipment, and electrical networks. GDTs are used to protect electrical installations from voltage surges caused by lightning or other sources. The CG32.7LTR is a GDT arrester designed to protect low voltage DC applications

Overview of CG32.7LTR

The CG32.7LTR is a low-voltage DC arrester manufactured by CG Lightning Protection. The device is designed to be installed between two grounding rods or between a grounding rod and an electrical device. The arrester consists of two tubes: the primary protector and the secondary protector. The primary protector is designed to withstand up to 32KV of surge voltage, while the secondary protector is designed to limit the voltage to ≤7KV at the grounding point. The arrester also has a built-in safety fuse to prevent excessive current from flowing through the device.

Application Field of CG32.7LTR

The CG32.7LTR is mainly used for low-voltage DC applications such as battery systems, photovoltaic systems, transportation systems, machine tools, and electrical equipment. It can also be used in RF applications, such as wireless communication systems and microwave links. The device is designed to protect DC installations from lightning-induced surges of up to 32KV, as well as other forms of overvoltages such as those caused by static electricity, faults in electrical installations, or sudden fluctuations in the electrical grid.

Working Principle of CG32.7LTR

GDT arresters work by using a combination of electricity and gas to absorb and limit the surge voltage. The CG32.7LTR has two tubes, a primary protector and a secondary protector, both filled with mixtures of H2 and Ar gases. When a surge enters the arrester, the voltage causes an ionization of the gas in the tubes, creating a conductive path for the electricity. The voltage is then limited by the secondary protector, which reduces it to a level safe for the DC application it\'s protecting.

The CG32.7LTR also has a built-in safety fuse designed to trip when the current passing through the arrester exceeds its rated value. This prevents the arrester from being damaged due to excessive current.

Conclusion

The CG32.7LTR is a GDT arrester designed to protect low voltage DC applications from lightning surges and other forms of overvoltage. The device consists of two tubes, a primary protector and a secondary protector, filled with mixtures of H2 and Ar gases. When a surge enters the arrester, the voltage causes an ionization of the gas in the tubes, creating a conductive path for the electricity and limiting the voltage to a safe level. The arrester has a built-in safety fuse designed to trip when the current passing through the arrester exceeds its rated value.
